So a few years ago I bought some Chlorella and I was taking a few tablets per day. There were no issues. One day out of the blue, I woke up a took my first two tablets. After I had gotten to work, I came down with a terrible sickness and I had to go home. I was real sick: I spent the next few hours vomiting. So I figured it was the chlorella and I started looking it up online and it appears that I am not alone in getting sick from chlorella. A few weeks later, I tried some more (a different bottle/lot) and the same thing happened. A few weeks later, I bought a green smoothie drink with just a smal dose of chlorella and I got midly sick (not to the earlier extent).
So my question is can I reintroduce myself to chlorella by taking a half pill or something and slowly incrementally increase the dosage? Does anyone have any experience in what might cause this or what to do about it? Thanks in advance
